Live drawing in Motion

Is there a way in Motion to draw on an object, live, like what the analysts do for a football game? Is this possible in motion? I would draw on a still photo more than likely. Any help here would be much appreciated!

I think I misstated. What I actually need to do is right it on, but record it. So after a little poking around, I discovered the Right-on" tool, and it looks like it will work with the pens as I need. Thanks for replying.
